HDPE pipe (High Density Polyethylene pipe) is a pipe made of high-density polyethylene (HDPE for short). HDPE pipe is an alternative to traditional steel pipes and polyvinyl chloride drinking water pipes, with excellent performance and a wide range of application scenarios.
Performance characteristics:
Corrosion resistance: HDPE pipe has good corrosion resistance and can resist most domestic and industrial chemicals, especially chemicals in the soil.
Compression resistance: HDPE pipe has strong compression resistance and can withstand a certain amount of pressure, suitable for various complex soil environments.
Weather resistance: It has good weather resistance, including UV resistance and long-term thermal stability, suitable for various climatic conditions.
Smooth inner wall: The inner wall is smooth, the water flow resistance is small, the circulation capacity is strong, and the construction cost is saved.
Long service life: The service life is up to more than 50 years, with good wear resistance and wear resistance.
Application areas
Drainage system: HDPE pipes are widely used in drainage tasks such as rainwater, sewage, and farmland irrigation and drainage. They are suitable for drainage areas such as roads, railway roadbeds, subway projects, waste landfills, tunnels, green belts, sports fields, and slope protection caused by high water content.
Water supply system: Applicable to urban tap water pipe network systems, urban and rural drinking water pipes, chemical, chemical fiber, food, forestry, printing and dyeing, pharmaceutical, light industry, papermaking, metallurgy and other industrial liquid transportation pipelines.
Agricultural irrigation: Used for agricultural irrigation pipes, suitable for underground irrigation and drainage systems in agriculture and gardening.
Other uses: Also suitable for postal and telecommunications lines, power wire protection casings, mining mortar transportation pipelines, etc.
Manufacturing process and material properties
HDPE pipes are made by extrusion molding process and have a unique double corrugated structure, which improves the external pressure strength and wear resistance of the product. Its raw material is high-density polyethylene resin, which has excellent electrical properties and impact resistance and is suitable for various processing methods such as sheet extrusion, film extrusion, pipe or profile extrusion, blow molding, injection molding and rotational molding.
